Also, find the speed of the train if the time taken for the train to travel the whole distance is 8 hrs

• A. 1600 km, 350 km/hr
• B. 800 km, 375 km/hr
• C. 1800 km, 300 km/hr
• D. 480 km, 380 km/hr

Answer 1

Answer: (B)

800 km, 375 km/hr

Suresh travelled 1200 km by air which form (2/5) of his trip.
Then total distance of journey=$\frac{5}{2}\times 1200=3000km$
Suresh travelled $\frac{1}{3}$of journey by car =$\frac{1}{3}\times 3000=1000km$
Then suresh travelled distance by train =3000-1200-1000=800 km
If whole journey by train in 8 hours
So speed of train=$\frac{3000}{8}$=375 km/Hr
